Information on New Energy Information on New Energy Introduction

1, new energy (NE): also known as unconventional energy. It refers to various forms of energy other than conventional energy. It refers to energy sources that have just begun to be developed and utilized or are being actively researched and are yet to be promoted, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy.

2, Definition: 1980 (Geng Shen year) the United Nations convened the "United Nations Conference on New and Renewable Sources of Energy" on the definition of new energy: new technologies and new materials as the basis for modernizing the development and use of traditional renewable energy sources, inexhaustible, renewable energy to replace the resources, limited, environmentally polluting chemical energy. limited, environmentally polluting fossil energy, focusing on the development of solar energy, wind energy, biomass energy, tidal energy, geothermal energy, hydrogen energy and nuclear energy (atomic energy).

3. New energy generally refers to renewable energy sources that are developed and utilized on the basis of new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy and tidal energy, as well as the thermal cycle between the surface of the oceans and the deep; in addition, there are also hydrogen, biogas, alcohol, methanol, etc., and the energy sources that have already been widely utilized, such as coal, petroleum, natural gas, and hydroelectricity, are called conventional energy sources. With the finiteness of conventional energy and the increasing prominence of environmental problems, new energy with environmental protection and renewable qualities is getting more and more attention from all countries.

4. New energy sources that can form an industry in China mainly include hydroelectric energy (mainly referring to small hydropower plants), wind energy, biomass energy, solar energy, geothermal energy, etc., which are clean energy sources that can be recycled and utilized. The development of new energy industry is not only an effective means of supplementing the entire energy supply system, but also an important measure for environmental management and ecological protection, and the ultimate energy choice to meet the needs of sustainable development of human society.

5. Generally speaking, conventional energy refers to the more technically mature and has been utilized on a large scale, while new energy usually refers to the large-scale use of energy has not yet been actively researched and developed. Therefore, coal, oil, natural gas and large and medium-sized hydropower are regarded as conventional energy sources, while solar energy, wind energy, modern biomass energy, geothermal energy, ocean energy and hydrogen energy are regarded as new energy sources. With technological progress and the establishment of the concept of sustainable development, industrial and domestic organic waste, which has been regarded as garbage in the past, has been re-recognized as a kind of energy resource utilization of materials and subject to in-depth research and development and utilization, therefore, the resource utilization of waste can also be regarded as a form of new energy technology. Newly developed and utilized by human beings, the energy resources to be further researched and developed are called new energy, relative to conventional energy, in different historical periods and scientific and technological levels, new energy has different contents. In today's society, new energy usually refers to solar energy, wind energy, geothermal energy, hydrogen energy and so on.
